Hazard lights ..... on a budget

Post by mrmorrisminor »

Hi,
I'm investigating the option of adding hazards to the Mog. Been looking at the kits available but we are on a restricted budget so was wondering if anyone had wired their own relay in (they seem reasonably priced) and what is involved in connecting it all up. ......

Shouldn't be too expensive, you could even get a cheap second hand flasher unit from a scrap yard a cheap flip switch and.blend it in to your indicator wiring with minimal effort or cost.

That's what I was hoping for. I have identified the wiring coming out of the indicator switch which gives the two supplies to the indicators. What I am not sure about is whether I would need a double poled switch to keep the two sides separate when the hazards are off to stop both sides flashing when the indicators are used. (I have roughed out the circuit diagram and the way I'm thinking of risks linking the two sides together.....)

I reckon a double pole switch should sort that.

Or a double pole relay....... Switch the relay with a simple 555 timer.

Don't hazard lights have a separate flasher in that circuit? At the very least you should use a new flasher that is not load dependent for its flash frequency. The sort you use with a trailer would probably work.

I used a hazard kit, the pull knob used the hole vacated by the manual washer pump when I converted to electric. The hazards have their own flasher as it needs to work when the ignition is off and overrides the indicators if the ignition is on.

I think there's supposed to be a warning light too. Purpose-made hazard light switches disable the indicators (eg. by cutting the power to the flasher unit) when they are on, otherwise the lights will behave oddly if you forget to cancel the indicators manually.

Thank you for the ideas. I have come up with a system that looks good on paper, using a double throw relay to transfer the main live away from the flasher relay to my new hazard relay and high ampage diodes to prevent any reverse flow back to the indicator circuit. With regard to the warning light, does it have to be an independent one (in view of rules and regs) or would it be acceptable to use the existing green light on the end of the stalk? (I think I have found a way of connecting it to both systems without interference)
So far the price tag is £10 including bullet connectors etc.......

Perhaps I'm misunderstanding your description, but instead of using the relay to switch power from one flasher to the other, I would wire it such that the hazard switch supplies the hazard flasher from a permanent live, while also energising a double pole relay that disconnects the existing supply to the indicator relay. That way the indicators only work with the ignition on but the hazards work regardless. Alternatively I think if you used a DPDT switch you could do away with the relay.

As I posted I spotted my error, indeed a permanent live (not ignition) to the hazard unit would be needed. at the moment I'm looking at maplin for the DT relay, cant see DPDT, any other suppliers to recommend?
I will be putting it together over the next couple of weeks so we'll see how we get on.

I mean use a DPDT switch instead of a relay: in one direction one of the poles connects the indicator flasher to the ignition-switched live, and in the other direction the other pole connects the hazard flasher to the permanent live.

Can't see why the stalk green light would be unacceptable......
Personally - I don't see the point of 'hazards' since everyone just ignores them anyway........

Found an appropriate DPDT push switch so that is much better than the faf of relay :D now down to £8 :D :D

What about this idea?

The switch is from a Mini, the real kind, and does the job of disconnecting the indicator flasher circuit and then connecting the hazard flasher to both sides of the indicators. All you need extra is the hazard flasher unit and the switch.

Or if you want a straightforward life try one of these: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0471165943. Only 4 wires and works perfectly, complete doddle to fit. If you remove the driver's side glove box and use bullet connectors you can connect straight into the existing (green) indicator wires.

Switch is small and can be fitted discretely but is still MOT complaint with the red flashing light.

Up to you...
